How much electricity do appliances use?

I'm just trying to get a vague idea, I know it costs roughly 23p per kWh but can't seem to find anywhere with estimates of energy use for specific appliances on Google.How many kWh would the following use (just a rough estimation)

-oven at 180 degrees for 30 mins-fridgefreezer for 24 hours-tv (small large backed old version) and DVD player for an hour-laptop for an hour-lightbulb for an hour-phone charger for an hour-radio for an hour

you need to look at the power reating on the appliance. Eg a IKw appliance will use one KW in an hour so it will take a 100 watt light bulb 10 hours to use the same. Generally heating appliances like immersions and kettles use the most, stuff like radios use very little. A 3 KW immersion will take 20 mins to use one KWhour

depends on the appliance. Look at the label on the back, or in the instruction manual.

power used equals volts x amps. The figure for volts is 240. The figure for amps is on the appliance. The answer will come out in watts, divide by 1000 for your kilowatts. Use a kilowatt for one hour and it costs you your 23p. (pricey tariff BTW).
